Contaminants in ZeoBak

[cwatkins]

I picked up a new small bottle of zeobak 2 weeks ago from a big LFS here in the lower mainland, and today when I cracked it open for the first time to use it, I noticed there's white wormy looking contaminants in the dropper.

Anyone else ever experience this? I'm wondering if they're good bacteria, but I think I'm going to exchange it tomorrow anyway...

Zeo is already enough of an unknown, I don't want to start putting clearly odd looking things into my tank
